The Installation Gap: Ensuring Your Fit-Out Does Not Void Certification

Precision engineering of made-to-measure fire doors at Pyro Doors factory in Greenock.

In the construction industry, the specification of high-performance products is only half the battle. For trade professionals and contractors, the critical challenge lies in the installation. Even the most robust, third-party certified fire door can fail to perform if the installation parameters do not strictly adhere to the tested evidence.

It is a common misconception that certification belongs solely to the door leaf. In reality, fire resistance is a property of the complete doorset installation. BM TRADA certification verifies that the product manufacturing meets rigorous standards for fire resistance, smoke leakage, and structural integrity. However, once that door reaches the site, the responsibility shifts to the installation team to maintain that integrity.

A frequent issue on commercial fit-outs is the attempt to force “stock” size doors into non-standard structural openings. Excessive planing of lippings or large gaps between the door leaf and frame (exceeding the 3-4mm tolerance) can catastrophic compromise the intumescent seal performance.

This is why Pyrodoor provides custom-built solutions. By engineering our FD30 and FD60 doorsets to measure, we eliminate the need for extensive on-site modification. This ensures that the door fits the aperture precisely, maintaining the validity of the certification and reducing the risk of remedial snagging work.

Substituting factory-specified ironmongery for generic alternatives is another significant risk factor. To guarantee compliance, fire doors must be fitted with compatible, fire-rated hinges, closers, and locks. Our doorsets are available with factory-fitted ironmongery to ensure seamless integration and total compliance.

As a contractor, your reputation relies on delivering compliant projects on time and on budget. Do not risk liability by cutting corners on installation. Partner with a manufacturer that builds to your specific measurements.
